DA405 Very High Viscosity High Solid PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC NSF Certified for Extreme Wastewater Treatment and Sludge Thickening
PolyDADMAC, also known as PDADMAC, PDMDAAC, PolyDMDAAC, or Poly (DADMAC), is a high charge density cationic polymer widely used in advanced water treatment processes.
DA405 is the highest viscosity grade within the 40% solid BLU DA Series, specifically engineered for extreme treatment conditions requiring maximum floc strength, superior bridging capability, and advanced solid-liquid separation.
Compared with DA404, DA405 delivers ultra-dense flocs, enhanced sludge compaction, and superior settling performance, making it the ideal choice for the most challenging wastewater scenarios.
Bluwat Chemicals is a professional manufacturer of water treatment chemicals with over 25 years of experience, exporting to more than 80 countries. We provide customized solutions supported by laboratory testing and real application data.
Our PolyDADMAC products are NSF certified for drinking water treatment chemicals, ensuring compliance with strict international standards and enabling safe application in potable water systems.
